Law of Sines: Ambiguous Case For any: I. Model Problems In the following example you will find the possible measures of an angle given the sine of the Law of SinesCosines Word Problems 1. A post is supported by two wires (one on each side going in opposite directions) creating an angle of 80 between the wires. Use of the Law of Cosines involves a simple equation, but the solution may involve the use of the quadratic formula. It is important to set a calculator for degrees. The law of sines formula allows us to set up a proportion of opposite sideangles (ok, well actually you're taking the sine of an angle and its opposite side). File Size: kb: File Type: Download File.
